However removing the curation rewards would do more bad than good things.
Not everyone have the talent/skills to write high quality blog post and the earnings of our posts are depending on the people, who upvote the posts.
And the amount of each upvote is able to give is depending on how much Steem Power the user have.
The curation rewards gives Steem Power to the accounts, who vote on posts/comments and the more Steem Power we have, the more we are able to give in a single upvote.
So the curation rewards are helping the whole community in the long run.
